2. Electrolyte is a term with a wide meaning. When it is used in different industries, the content it represents is very different. There are electrolytes (also called electrolytes) in organisms, electrolytes used in battery industry, electrolytic capacitors, supercapacitors and other industries. Electrolyte is the medium (corrosive) used in chemical batteries and electrolytic capacitors, which provides ions for their normal work. And ensure that the chemical reactions occurring in the work are reversible.
3. Lithium-ion battery: It is a kind of secondary battery (rechargeable battery), which mainly works by the movement of lithium ion between the positive electrode and the negative electrode. In the process of charging and discharging, Li+ is embedded and extracted between the two electrodes: during charging, Li+ is extracted from the positive electrode and embedded into the negative electrode through electrolyte, and the negative electrode is in a lithium-rich state; The opposite is true when discharging. Batteries generally use lithium-containing materials as electrodes, which is the representative of modern high-performance batteries. Lithium batteries are divided into lithium batteries and lithium-ion batteries. Both mobile phones and laptops use lithium-ion batteries, also known as lithium batteries, but real lithium batteries are rarely used in daily electronic products because of their great danger.
